Judges announce the Best Article Award for the inaugural 2013 Earth Science Technology Showcase. The showcase features 10 articles on current Earth-observing technology development projects, authored by principal investigators from NASA’s Earth Science Technology Office (ESTO).
RAVAN will demonstrate two key technologies that enable accurate, absolute Earth radiation measurements using a remarkably small instrument: a vertically aligned carbon nanotube forest absorber and a gallium fixed-point blackbody as a calibration transfer standard.
The Far-Infrared Spectroscopy of the Troposphere (FIRST) instrument has been developed to observe a portion of the infrared spectrum relevant to climate
In a collaboration of NASA’s Jet Propulsion Laboratory and the Hydro and Agro Informatics Institute of Thailand, sensorweb technologies are being used to enhance monitoring of flooding in Thailand. This Thailand Flood Sensorweb utilizes automation techniques to detect flooded areas, alert interested parties, and deliver imagery.
The authors have developed a novel broadband antenna technology that enables remote sensing measurements over the X- to Ka-band microwave spectrum from a single aperture. The antenna technology is integrated with an airborne X- and Ku-band synthetic aperture radar and K-and Ka-band radiometer for measuring the spatial distribution of surface snow.
The authors describe an atmospheric methane lidar in development, which is capable of making continuous measurements from orbit in sunlight and darkness at all latitudes.
This paper describes a new, highly efficient laser altimeter capable of mapping the Earth’s vegetation cover and the soil surface through foliage
To reveal multiscale processes from high-resolution, multidimensional Earth science data, we have developed the parallel version of the ensemble empirical model decomposition (PEEMD) method with a three-level parallelism. In this study, we illustrate the performance of the PEEMD in extracting tropical wave components from idealized tropical wave solutions and large-scale environmental flows associated with Hurricane Sandy.
This paper describes the first fiber-coupled, distributed-feedback semiconductor lasers operating near 2.051 um wavelength with record high output power. Among the novel applications and instruments they enable are carbon dioxide concentration measurements in air.
Climate models and observations are generated from a variety of sources and by a variety of institutions. The Regional Climate Model Evaluation System provides the necessary software and architecture to easily and rapidly perform model evaluation activities.
